Attached Link: ZBrush Hard Surface Techniques 2

Of the 4 major packages, only Modo is reasonable priced. As Modo also is very new and modern that speaks for Modo. But if money is no concern C4D have the best integration with Poser (besides having GoZ too). If you can afford only 1 program better to start with ZBrush. I would not have said that before version 4R2 but 4R2 and 4R2b changes everything.

ZBrush is like a rollercoaster..
